What "questionable content"? I mean, they've always had that, I'm just curious what specifically you're talking about.

As for the art style, yes, Mike has purposely refused to stick to any specific style and just kind of does what he wants. Which has resulted in some art a lot of people aren't fond of (myself included) but at least he's still trying new things. I mean, in a world where most comics that gain notoriety are deliberately bad or simplistic art that often isn't even colored, it's nice that PA is still trucking along actually drawing real art.

Honestly, Penny Arcade has kind of just become like any comic strip: you read it every now and again, you aren't checking in regularly. And it's only partially the comics, the other half are Jerry's attached blog posts which are usually worth a read.

I keep coming back to it because it's interesting seeing these guys grow up. There was one recently where Gabe tells the reader "if you were reading early Penny Arcade in college, it's time to get your prostate checked".
